         DRILLING STARTS ON NEW YANKEE PROJECT

     South  Jordan,  Utah --- Pioneer  Oil and Gas (OTC  Bulletin  Board:  PIOL)
announced  today that it had commenced  drilling on its Yankee Mine West Project
in White Pine County, Nevada.

     Pioneer has an 18.75 percent carried  interest to casing point on the first
three wells drilled on the prospect.

     Don J.  Colton,  President  of Pioneer Oil and Gas stated,  "This well is a
follow-up to the Yankee Mine 27-23x well drilled in 1992.  Both wells are on the
same large north-south  anticline." Just east of the well is the Yankee Mine oil
seep that was featured in a 1991, Oil and Gas Journal article.

     In another  development  Pioneer Oil and Gas has received  earnest money on
its Uinta Basin  Overpressured  Gas Prospect in Utah.  Closing is scheduled  for
January 2005.

     Finally,  Pioneer Oil and Gas has also acquired a fifty percent interest in
over 60,000 acres in the exciting new Central Utah  Overthrust  Play.  Wolverine
Gas and Oil's discovery  opened this play in May 2004.  Wolverine is reported to
be producing  over 4,000  barrels of oil a day from the first two wells  drilled
and is in the  process  of  drilling  a third  well.  Pioneer  feels  it is well
positioned in this play with  interests in over 10 prospects that appear to have
oil potential.

     Statements concerning future financial results,  production,  expenditures,
reserve  estimates,  and  other  items  are  forward-looking  statements.  These
statements  are  based on  assumptions  concerning  commodity  prices,  drilling
results and other factors management  believes are reasonable based on currently
available  information;  however,  management's  assumptions  and the  Company's
future performance are both subject to a wide range of business risks, and there
is no assurance that these goals and projections can or will be met.
